I plug in my headset and PC detects it. But the problem is that there is no sound coming trough and no sound is being detected (by the microphone). This happens on the front and the back jacks. But it does work if i plug them in the monitor, which is OK, but there is no microphone jack on it. As far as I know, my drivers are up to date, I'm using Realtek HD Audio Manager and use GAMECOM 388 headset. I did set it as a default playback device and the green bars are jumping up and down but still no sound (in or out). I checked and nothing is muted. I am thinking that maybe the graphic card may be overriding the default audio, but I'm not sure. As mentioned before, sound works trough monitor (connected to graphic card via HDMI).
